## Is 774 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 774 is about 27.821.

Thus, the square root of 774 is not an integer, and therefore 774 is not a square number.

## What is the square number of 774?

The square of a number (here 774) is the result of the product of this number (774) by itself (i.e., 774 × 774); the square of 774 is sometimes called "raising 774 to the power 2", or "774 squared".

The square of 774 is 599 076 because 774 × 774 = 7742 = 599 076.

As a consequence, 774 is the square root of 599 076.

## Number of digits of 774

774 is a number with 3 digits.

## What are the multiples of 774?

The multiples of 774 are all integers evenly divisible by 774, that is all numbers such that the remainder of the division by 774 is zero. There are infinitely many multiples of 774. The smallest multiples of 774 are:

## How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 774). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 27.821). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
